When the heating came on this after (timer - 2 periods morning and evening) there was a loud banging noise transmitted through the central heating pipes every 20 seconds or so. When I went to the airing cupboard, I found the noise was coming from the above valve. The lever on the side moved from A to B and then snapped back to A at which point the noise occurred.
Clearly there is a problem with the valve. From the description, can anybody say whether the valve is jammed or is there an electrical fault. Can the electrical bit be removed from the valve bit so that I can check whether the valve bit moves easily and if so, how? Is there a common fault with these valves that shows itself with my symptoms?
Thanks CVB
